I can't manipulate the input fields without modifying the plugin but I can add classes. Currently I have:

<input class="clearfields" type="text" value="enter name etc">

Currently this will clear any field with the class .clearfields which is good but I only want to clear just the field the user has clicked in. At the moment it clears everything (name, email, company etc) as all fields have the class applied.

Second to this, with my current setup even though the form appears to send after clicking the submit button the email does not arrive so something is up with my code.
